[linux-audio-user] jack and setuid

Hello Lists, I don't know, where ich can fix my little problem. Maybe i 've missed some explanations and/or haven't read my mails good enough. anyway, i try to install a linuxbox for audio on slackware i have installed slackware and patching the kernel 2.6.14 vanilla with patch-2.6.14-rt2. Then i installed the set_rtlimits1.1.0 software, because Slackware has no PAM. First. this must be all for audio in realtime , is this right?? then i have to set the setuid. aus root i have done bash-3.00$ su Password: bash-3.00# chmod ugo+s /usr/local/bin/jackd bash-3.00# exit bash-3.00$ ls -la /usr/local/bin/jackd -rwsr-sr-x 1 root root 206476 2005-11-01 15:23 /usr/local/bin/jackd bash-3.00$ whoami soundroom bash-3.00$ jackd -dalsa& [1] 3202 bash-3.00$ jackd 0.100.0 Copyright 2001-2005 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK compiled with System V SHM support. loading driver .. creating alsa driver ... hw:0|hw:0|1024|2|48000|0|0|nomon|swmeter|-|32bit control device hw:0 configuring for 48000Hz, period = 1024 frames, buffer = 2 periods nperiods = 2 for capture nperiods = 2 for playback bash-3.00$ ps -aux [..] root 3202 0.0 0.4 10472 2380 pts/1 S 12:03 0:00 jackd -dalsa root 3203 0.0 0.4 10472 2380 pts/1 R 12:03 0:00 jackd -dalsa root 3204 0.0 0.4 10472 2380 pts/1 S 12:03 0:00 jackd -dalsa root 3205 0.0 0.4 10472 2380 pts/1 S 12:03 0:00 jackd -dalsa root 3206 0.2 0.4 10472 2380 pts/1 S 12:03 0:00 jackd -dalsa [..] bash-3.00$ jack_lsp JACK server not running why i can't use jack an normal user? what have i missed? why there are 5 processes of jack? is this a secure way? do i need every application as suid?
